v Suffolk, respectively, and State of Massachusetts, have invented certain new and useful Improvements in Packages and the Method of Making the Same, of which the following is a specification.

This invention relates to wrapped articles and the method of wrapping them, and has special reference to the wrapping of loaves of bread, the present application being a division of our application for bread-wrapping machines filed September 11, 1908, Serial No. 452,651, and which became Patent 1,064,964.. j

The invention has for its object the provision of packages of merchandise so wrapped and secured that the several folds of thewrapper are retained in place by overlying folds, the entire folded wrapper being retained in place by the final fold or flap of the wrapper, whereby it may be finally secured-at one point.

In carrying out the invention, the steps of the folding are so timed in relation to each other that the article is inclosed by the wrapper, the latter having successive folds which are held in place as the wrapping about the article, Fi

proceeds, the wrapper being finally folded and secured at a single point.

Referring to the accompanying drawings,-Figures 1 to 8, inclusive, are views in perspective of an article and wrapper, showing the several steps of folding the wrapper g. 8 showing-the wrapper completely folded about thea-r'ticle;

The method of wrapping articles under I this invention is as follows: An article such as a loaf of bread a is placedupon a wrapper 6, as shown in Fig.1, the loaf of bread being here illustrated as in inverted position, as the tops, ends and sides of loaves of bread are generally of irregular shape, while the bottom is practically flat and smooth which permits of the final folds of the wrapper being smoothly and compactly-made. In the next step of folding the wrapper b is folded lengthwise in a U-shaped fold about three sides of the loaf a, the wrapper projecting beyond the ends of the article and beyond its top, as shown in Fig. 2. In this position, end portions 10 of the wrapper are first folded in against the ends of the loaf a, which act of folding forms folded, tapering, projecting portions 11, l2,'extending beyond the ends of the article, as shown in Fig. 3. One of said folded, tapering, projecting portions 11, is then folded at each end of the loaf a against the folded end portions 10 of the wrapper at the ends of the loaf, as shown in Fig. 4. The other tapering, folded end portions 12 at the ends of the loaf a are then folded in overlapping positions over said tapering, folded end portions 11, as shown in Fig. 5. In this position the wrapper projects in folded position past the ends of the loaf and the overlapping folded portions are retained in place at the ends of the loaf. The projecting, folded or overlapping portions 13, 14, at the ends of the article are'then folded against the fiat surface of the loaf at oppositeends, as shown in Fig. 6. One of the side remaining portions 15 of the wrapper, projecting past the flat face of the article, is then folded over said end folded portions 13, 14. as shown in Fig. 7, and the other remaining projecting portion 16 at the side of the article is then f0lded down upon the vfolded portions of the wrapper, lying against the flat surface of the article, as shown in Fig. 8, and secured in place in any suitable manner. One way of securing the folds is by means of a suitable adhesive applied to the edge of the wrapper, as indicated at 17 in Fig. 3, so that, in the final folding of the wrapper, the fold having the adhesive is located beneath the final fold of the Wrapper, so that as the final fold is made as indicated in Fig. 8, the adhesive serves to fasten it. We do not limit ourselves, of course, to this particular way of sealing the'final fold.

The method of folding described provides a package which is securely wrapped and has all of the folds of the wrapper smoothly v the flap 15 and the flat surface of the article.

In either case, the final flap 16 which, in practice, is preferably sealed, confines and holds the opposite flap 15 and also the corners against the substantially flat bottom surface of the loaf. The successive folding operations are such as to cause the end folds to be so tucked inside other portions of the Wrapper that said end folds will be held by the final flap.

It will be observed that the package when complete, has the usually irregular top and two sides and portions of the ends of the loaf covered by only a single thickness of the wrapper material, and consequently, there can be no bunching of the wrapper material over lumps or swells at these points. The ends of'the package, of course, have some overlapped portions of double thickness, comprising the upper portions of the and folds 11, 12, but portions of these same folds 11, 12, including the corners 13, 14, are laid against the bottom of the package and confined there. The method of folding is such that the portions 11, 12, at the ends, of the packages are very smooth, and are held fiat and do not project so as to be caught upon or by other objects, in such manneras to permit end portions 'to be pulled out so as to open or partially open the package. In other words, the middle portions 10 of the end folds are overlapped by doubled portions 11, 12, and the latter are held securely, due to the fact that the portions 13, 14, are drawn down and carried in under the bottom and held there, so that there is no bunching of the Wrapper material at the ends of the package, such as would be liable to be pulledout.

The terms designating certain portions of the merchandise or complete package, such as top ends, sides, and bottom are employed in a relative sense for purposes of description, and without intent to limit ourselves thereby. It has been more convenient to explain the invention by the employment of terms such as quoted, but it will be obvious that if the merchandise were of other form, such terms might not so clearly apply as when the merchandise is elongated in form. So far as the term bottom is concerned, it is to be understood that we mean that portion of the package which is substantially flat and which'supports or includes the final folds which are, in practice, preferably sealed.

It is to be understood that the invention relates especially to the packaging of articles 'ture and prevent evaporation.

Loaves of bread even when from one baking, widely differ from each other in size and shape, this being due to the unequal rising of the loaves above the top of the pan, and to the fact that side and end portions frequently overhang the top edges of the pan. The bottom of the loaf is the only reliably uniform and substantially fiat surface; hence, it is necessary for the best results to assemble theloaf and the wrapper that the portion which is the top of the loaf will be in contact with the middle portion of the wrapper, as shown in Figs. 1 and 2. After the fold shown in Fig. 2 has been produced, the successive operations bend the middle end portions 10 of the wrapper against the end of the loaf, while still leavsealing of the final flap, without requiring any separate treatment of the end portions by an adhesive. Although the loaves are frequently very irregular, the wrapper when applied entirely excludes moisture and prevents evaporation although it is of but a single thickness. As shown in the drawings, the wrapper is continuous, by which we mean that it is in a single piece and has no cuts or slits Within its margin. Therefore, although it is of a single thickness, the special folds result in entirely excluding mois- Since the wrapper is flexible it closely fits the loaves even when irregularyalthough the figures of the drawings show the bends and corners with sharp angles, this latter being done to avoid confusion in illustrating the wraps or folds. All of the final folds are overlapped and secured at the bottom of the article, while there is but a single thickness of the wrapper over the top and sides of the article.

We claim:

1. The herein described method of wrapping bread which consists in assembling a loaf and a wrapper with the top of the loaf in contact with the middle portion of the wrapper, then simultaneously folding the plane of the bottom of the loaf, simultaneously folding edge portions of the wrapper against the ends of the loaf to form outstanding corner folds, folding said corner folds in overlapping position against the ends of the loaf, and then successively turning in different edge portions of the wrapper and overlapping them against said bottom of the loaf with a single final flap or edge portion overlying all other turned in edge portions.

'2. lhe herein described method of wrapping bread which consists in assembling a loaf and wrapper with the top of the loaf in contact with the middle portion of the wrapper, then simultaneously folding the wrapper against two opposite sides of the loaf with edge portions of the wrapper projecting substantially equally beyond the plane of the'bottomof the loaf, simulta' neously folding edge portions ofthe wrapper against the ends of the loaf to form outstanding corner folds, folding said corner folds in overlapping position against the ends of the loaf, then successively turning in difierent edge portions of the wrapper and overlapping them against said bottom of the loaf with a single final flap or edge portion overlying all other turned in edge portions, and sealing said flap directly to the underlying portions.

8. The herein described method of wrapping loaves of bread which consists in folding a wrapper in longitudinal U-shape over the top and two sides of a loaf with the sides and ends of the wrapper projectingbeyond the loaf, folding the ends of the wrapper with an inner fold and outer folds overlapping the inner fold, folding the folded ends of the wrapper over the bottom of the loaf adjacent to its ends, folding the side projecting portions of the wrapper over the said overlapping portions, and securing the final folded portions together.

4. The method of wrapping loaves of bread which consists in folding a rectangular wrapper across the top of theloaf and against the two, sides thereof, the middle portion of the wrapper contacting with the top of'the loaf, then successively bending end portions of the wrapper against the ends of the loaf, leaving the side edges of the wrapper unfolded, then turning doubled portions of the wrapper toward each other and overlapping them against the ends of the loaf, and then overlapping the side tangular flexible wrapper of a single thickness, said wrapper having its middle portion in contact with the top of the loaf and having all four of its corners supported against the bottom of the loaf with a single final flap or edge portion overlying all other turned in edge portions, mid-length edge portions of the wrapper being in contact with the ends of the loaf, the Wrapper having oppositely laid folded flaps at each end which overlie said mid-length edge portions and hold themsnugly against end portions of the loaf.

1 6. A package comprising a loaf of bread completely inclosed in a substantially rectangular flexible wrapper of single thickness, said wrapper having its middle portion in contact with the top of the loaf and having all four of its corners supported against the bottom of the loaf with a single final flap or edge portion overlying all other HENRI A.
